STATES NITE AMOS WALLACE, OF MARENGO, ILLINOIS.

PORTABLE WIND -ENGINE.

SPECIFICATION forming part of Letters Patent No. 666,946, dated January 29, 1901.

Application filed August 10, 1900. Serial No- 26,490. (No model.)

To all whom, it nuty concern: 7

Be it known that 1, Autos WALLACE, a citizen of the United States, residing at Marengo, in the countyof McI-Ienry and State of Illinois, have invented certain new and useful Improvements in Portable Wind-Engines, of which the following is a specification.

The object of this invention is to construct awind-engine mounted upon awheeled frame in order that it may be moved about and placed near the work it is to do.

111 the accompanying'drawings, Figure 1 is a plan view of my improved portable windengine. Fig. 2 is a side elevation. Fig. 3is a side elevation of one of the sails, showing the spring connection. Fig. 4 is an isometrical representation of the bolt employed to clamp the spring rod.

The wind engine is mounted on a main frame, consisting of the end bars 1 and 2, side bars 3, and a center bar 4, joined together in any suitable manner. To the rear end bar 1 is secured an axle 5, and upon the axle is located supporting-wheels 6. From the front end bar 2 is pivotally connected an axle 7, which supports Wheels 8, and to the axle is connected a tongue 9. To the end bar 1 rises a support 10, and boxes 11 are secured to its upper face and support a shaft 12. One end of the shaft has a pulley 13 connected thereto, and its other end supports a wind-wheel, the details of construction of which will be explained hereinafter. The front end bar2 supports a bracket 14, to which are connected boxes 15, supporting a shaft 16, to one end of which is connected a pulley 17 and a wind- Wheel connected to its other end. The center bar 4 has two brackets 18 connected thereto, each supporting a box 19, the boxes supporting a shaft 20, and the ends of the shaft have pulleys 21 and 22 connected thereto. A belt 23 connects the pulleys l3 and 20, and a belt 24 connects the pulleys 17 and 20. The pulley 21 is designed to receive a belt to transmit power to the required machine.

The wind-wheels supported by the shafts 12 and 16 are of like construction, and each wheel has a series of sails, each of like construction. It will therefore be only necessary to describe the general construction of one wind-wheel and of one sail. The wind-wheels are composed of a central hub 25, secured to 'the shaft driving it. Spokes 26 radiate from the hub and supporta rim 27. The rim supports a series of rods 28, each rod having a headed end 29. Upon each rod is pivotally supported a'sail 30,and to the sail is connected an arm 31, supporting a weight 32. A springrod 33 has a connection with the sail, and its other end has an adjustable connection with the hub 25 of the Wind-wheel in a manner to vary its torsional force, and by means of a bolt 34, passing through the hub, receiving a nut 35 on its free end. The head 36 of the bolt has a recess 37 in its inner face, within which is located the end of the spring-rod 33; By turning the spring-rod its torsional force can be varied and can be held by the clamp ing device. The action of the spring-rod is to hold the sail in the wind, and when the wind becomes too strong the spring-rod will allow the sail to yield, thereby preventing the breakage of the parts. The rod 31 and its Weight 32 act as a counterbalance to the sail, and during the downward half of the revolution of the wind-wheel the weight will hold the sail in the wind against the weight of the sail. A stop 38 extends from the rim of the wind- Wheel and. prevents the sail from taking only so much Wind. By means of the two windwheels having a connection with a common driving-pulley greater power can be obtained.

I claim as my invention In a wind-engine, the combination of a horizontal shaft a rim supported by the shaft, arms extending radially from the rim, a sail pivotally supported by each arm, a weight connected to each sail, a stop for each sail extending from the rim and a spring having a torsional action connected to each sail and adj ustably connected to the wheel proper.

AMOS WALLACE.
